IMAGING DISTAL END OF MULTIMODE FIBER

摘要

Where a multimode fiber is used for light delivery in a microscope system and a transverse distribution of light exiting a distal end of the fiber is substantially uniform, the distal end is imaged onto a plane of a sample to be probed by the microscope system, or at a conjugate plane. Alternatively, the distal end is imaged onto a plane sufficiently close to the sample plane or the conjugate plane such that a radiant intensity of light at the sample plane or the conjugate plane is substantially uniform. In the case of a multi-focal confocal microscope system, the distal end of the multimode fiber is imaged onto a plane of a segmented focusing array. Alternatively the distal end is imaged onto a plane sufficiently close to the segmented focusing array plane such that a radiant intensity of the light at the segmented focusing array plane is substantially uniform.
